support for embedded GPU documents

Hi,We are interested in developing embedded GPU (E4690,E6760,E6460) drivers for embedded systems. We had access to discrete GPU documents in AMD Embedded Developer site with NDA. However, I could not see any documentation about certain features like DDK documents, 3D, shader and tv out (for E4690) register documents.I would like to know if there are additional documents/utilities for the discrete embedded GPUs (either public or by NDA).
